What type of resource is iron ore?
Iron is a natural resource. It is found in nature as Iron Ore, which is iron with oxygen and other impurities. These impurities are removed by heat treating the Iron Ore and melting away the impurities, due to different melting points of the impurities.
Why is limestone added to the blast furnace during the extraction of iron?
Iron ore contains the impurities sand and clay, which are silicon oxides. Limestone is added to remove these impurities.
How Is Iron Ore Purified using Carbon?
Iron ore, carbon (also called 'coke') and limestone are heated in a blast furnace. The carbon reacts with oxygen blasted into the furnace from the bottom to form carbon monoxide. Carbon monoxide then reduces the the iron ore to molten iron and becomes carbon dioxide in the process. The limestone in the furnace melts the impurities and decomposes to calcium oxide (quicklime). Quicklime and impurities mix together to form 'slag'. The slag floats on top of the molten iron so that the iron can be drained off at the bottom.
Is iron and iron ore the same?
no they are not the same because iron is a metal that is obtained from its ore called iron ore
What is the ore of iron called as?
Iron ore.
Is iron ore homogeneous?
no because it contains impurities

When oxygen is blown into pure iron to remove impurities Wont it react with Iron itself to give iron oxide?
Oxygen is not blown into pure iron, it is blown into molten iron ore (many impurities) and coke has been added to the mix as well. the coke reacts with the impurities and the oxygen to purify the iron ore.
What must be done to iron ore to produce element iron?
They need to smelt it to get all the impurities out
Is iron ore a homogeneous or heterogeneous substance?
Pure Iron is considered as Homogeneous. Whereas, Iron with rust or other impurities is Heterogeneous.
Why is limestone added to the blast furnace during the extraction of iron?
Iron ore contains the impurities sand and clay, which are silicon oxides. Limestone is added to remove these impurities.
What is the method for purifying iron?
After iron ore is mined it is crushed into a powder then injected into a blast furnace. Under the extreme temperatures the ore melts and since iron is more dense than the impurities, it sinks to the bottom. This leaves a film of "slag" (impurities) on top. The slag is then skimmed off so only the metal remains.
How did the kelly-Bessemer process help iron and steel production better?
It mixed impurities in the iron ore enough to eliminate the problem of weakening.
How did Bessemer allow better use of iron ore?
This technique involved injecting air into molten iron to remove the carbon and other impurities.
What did Henry Bessmer invent?
The method to make steel. The Bessemer method blows air into the hot iron ore to remove the impurities from the ore and this makes steel.
How did the Kelly Bessemer process help make iron and steel production better?
It mixed impurities in the iron ore enough to eliminate the problem of weakening.
